Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.

type when possible.
Fix type finalization of type parameters (always finalize in the context of the
class being parameterized and not in the enclosing class where the type
parameter is used).
Fix wrong generic optimization and added a test (a generic type instantiated
from a raw instantiator is not always raw).
Added printing of type argument vectors.

Local functions and function literals are unknown to the VM
until the enclosing function is compiled. This change introduces
a list of known closures per class, and a function to look up
the innermost closure at a given token index.
The debugger now checks whether there are newly discovered
closures when a function containing a pending breakpoint is
compiled. If necessary, the breakpoint is set to the inner
function.

On standalone dartium which has about 50000 tokens in the libraries (core, coreimpl, builtin, io etc.) this reduces the heap size by about 180kb. The size of the standalone snapshot buffer reduces by about 72kb.
Also moved the keyword symbol table to the object store so that it does not have to repopulated on every script compilation. Should benefit regular user script load times.

This change adds peer and callback arguments to the external byte array
constructor and moves the peer, callback, and data storage into a VM
peer object. At construction time, a weak persistent handle and VM
callback is associated with the VM peer. The VM callback will delete
the VM peer and invokes the user callback to reclaim the user peer.
This change also activates the callback support for the various classes of
external strings.

rather than an array of String and simplify code accordingly.
Rename the field holding type parameter bounds of a class.
Note: I retract my earlier suggestion to Srdjan to represent interfaces of a
class (as well as its canonical types) as a TypeArguments. This would require
more code to check for an empty array and for growing the array. Besides, these
are really arrays and have nothing to do with type arguments. I removed the
corresponding TODO(srdjan).

The purpose of this change is twofold:
1. Source in the bin directory can now use the same assertions as
source in the vm directory. The ASSERT macro used by the code
in runtime/bin was just defined to use assert from the standard
C library.
2. Moving other implementation parts from runtime/vm to
runtime/platform (e.g. classes Monitor and Mutex) for sharing
between runtime/bin and runtime/vm will be easier as these
implementations rely on these assertion macros.
Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.
All the code for asserts is still in the dart namespace.
Also re-arranged the order of includes to be alphabetically in
the files touched.

things that may go wrong while invoking the dart api.
Here are the four types of error:
- ApiError = the user misused one of the dart apis
- LanguageError = a language-level problem, e.g. compiler error
- UnhandledException = an uncaught exception made its way to the embedder
- UnwindError = a forced isolate interrupt
This cl is the first of a series. I plan to move the point of
creation for LanguageErrors into the Parser, etc. I also plan to move
the longjmp's out of dart_api_impl.cc. I also also plan to implement
UnwindErrors later.

This change introduces variable descriptors that describe the name, stack slot index, and source code stretch in which a variable is valid.
Activation frames in the stack trace now can enumerate the variables that are active in that frame.
Next step: fetch the value of variables from the stack.

- Introduce 3 kinds of snapshots (full, application script and messages)
- Added a dart API function to be used for generating an application snapshot
and for loading the script from an application snapshot.
Next step is to introduce special handling in the WriteTo and ReadFrom
snapshot functions for 'kind == Snapshot::kScript'

External strings refer to character data in memory located outside of
the managed heap. This memory is considered to be owned by the
embedding application. To help with the management of external
memory, the virtual machine allows the embedding application to
register for a "death notice" when an external string object is
garbage collected. A death notice takes the form of a callback
invoked by the garbage collector with the address of the external
memory. Death notices will be implemented in the garbage collector by
future commit.
